Preventing SCA

One of the most devastating aspects of sudden cardiac arrest is that it often strikes active, apparently healthy individuals. How then, can sudden cardiac arrest be prevented?

The first step is to lead a heart-healthy lifestyle.
 
  • Eat a heart-healthy diet.
  • Exercise regularly.
  • Lose weight if you are overweight or obese.
  • Take your medications as ordered by your doctor.
  • Drink alcohol only in moderation.
  • Do not smoke.
  • A heart-healthy lifestyle is important in the prevention of coronary artery disease and other heart conditions. Eighty percent of SCA victims have signs of coronary artery disease.

Many individuals do have signs or symptoms that could indicate an increased risk for sudden cardiac arrest.

  • An abnormal heart rate or rhythm (called an arrhythmia)
  • A rapid heart rate, even when at rest (tachycardia)
  • Episodes of fainting (syncope)
In addition, there are clear indicators that suggest high risk for sudden cardiac arrest.

  • Prior sudden cardiac arrest
  • Prior heart attack
  • Heart failure
 
Heart Failure, often called congestive heart failure or CHF, is a condition in which the heart is unable to pump enough blood to meet the needs of the body. The heart doesn't "fail" in the sense of ceasing to beat (as occurs during a heart attack). Rather, it weakens, usually over the course of months or years, so that it is unable to pump out all the blood that enters its chambers. As a result, fluids tend to build up in the lungs and tissues, causing congestion (hence the name "congestive" heart failure).
